Vocabulary flashcards covering carpal bones, tarsal bones, and cranial bones from the notes.

Scaphoid

Boat-shaped carpal on the thumb side; articulates with the radius and the trapezium/trapezoid.

Lunate

Moon-shaped central proximal carpal; articulates with radius, capitate, hamate, scaphoid, and triquetrum.

Triquetrum

Three-sided carpal on the pinky side; articulates with pisiform, hamate, and lunate.

Pisiform

Pea-shaped carpal on top of triquetrum; provides tendon attachment for flexor carpi ulnaris.

Trapezium

Wedge-shaped carpal under the thumb; articulates with the 1st metacarpal to enable thumb mobility.

Trapezoid

Wedge-shaped carpal between trapezium and capitate; articulates with the 2nd metacarpal.

Capitate

Largest carpal in the center; articulates with the 3rd metacarpal.

Hamate

Hook-shaped carpal on the pinky side; articulates with the 4th and 5th metacarpals.

Talus

Tarsal that forms the ankle joint; sits atop the calcaneus and articulates with the tibia and fibula.

Calcaneus

Heel bone; largest tarsal; attachment point for the Achilles tendon.

Navicular

Boat-shaped bone anterior to the talus; articulates with the medial, intermediate, and lateral cuneiforms.

Medial Cuneiform

Under the 1st metatarsal (big toe).

Intermediate Cuneiform

Under the 2nd metatarsal.

Lateral Cuneiform

Under the 3rd metatarsal.

Cuboid

Cube-shaped bone on the lateral foot; under the 4th and 5th metatarsals.

Frontal

Forehead bone forming part of the skull’s front; articulates with parietals, nasal bones, and zygomatic bones.

Parietal

Two bones forming the roof and sides of the skull; articulates with the frontal, occipital, temporal, and sphenoid.

Temporal

Bones on the lower sides of the skull; contain the ear canal and mastoid process; articulates with the parietal, occipital, sphenoid, and zygomatic.

Occipital

Back of the skull; contains the foramen magnum; articulates with the atlas (C1) and other cranial bones.

Sphenoid

Butterfly-shaped bone at the base of the skull; articulates with frontal, parietal, temporal, occipital, and ethmoid.

Ethmoid

Light, spongy bone between the eyes; forms part of the nasal cavity and septum; articulates with the sphenoid, frontal, and nasal bones.
